A whole NBA game lasts 48 minutes. This time is divided into four halves of each 12 minute block. In the case of a tie between the competing teams, this time can be extended. This is followed by overtime, in which the game continues until a winner is determined, lasting five minutes. If the score is still tied at the end of five minutes, then the first team to reach 15 points wins.
The first half of the game starts with players on both sides being awarded two-minute bursts of possession, during which they are allowed one shot and may use either hand. After eight minutes have passed, the teams change roles, so that now it is the defending champion who gets the first opportunity to shoot.
This routine is repeated twice more before moving on to the second half. The third quarter is played in the same manner as the first, except that there is no set order of shots for either team. Rather, each player is given a number of opportunities to score according to how much time has elapsed since the last basket was made. For example, if one player makes a free throw after three seconds have passed, but another doesn't get a chance until twenty-five seconds have gone by, then that player will have scored with seven seconds left in the third quarter.
The final quarter is called "replay" and it is here that controversy often arises over exactly what happened in the previous period.
Wiki is the answer. An NBA game lasts 48 minutes, divided into four quarters of 12 minutes each. However, regulation time is paused for several components of the game, including as fouls, out-of-bounds balls, timeouts, and a 15-minute intermission. The period of time that has elapsed since the last whistle was blown is called dead ball time.
There are two types of fouls: personal and defensive. A personal foul is committed by a player while defending against an opponent's shot or movement. It results in a free throw for the opposing team. A defensive foul is any foul committed by a player while guarding an opponent. Defensively, a player can also commit a flagrant foul by hitting the backboard with an open hand or punching it. Flagrants result in a three-point penalty and a fine for the offender. Otherwise, they are legal plays. There are five other categories of fouls: technical, offensive, reciprocal, double violations, and ejections. Technical fouls do not cause a break in the action of the game; they serve only to call attention to a violation by the opposing team or a player from either team. For example, if a player argues with a referee about a call, he or she would be issued a technical foul. Offensive fouls occur when a player shoots without being touched by a teammate; charges into the court while holding the ball; or commits any other offensive act intended to get away with a basket.
The game itself lasts 48 minutes (four 12-minute segments plus a 15-minute halftime). However, because the game clock frequently stops in basketball, games last around 2 1/2 hours, unless they go into overtime. The longest game in NBA history was played on February 11, 2001 between the Los Angeles Lakers and Boston Celtics. It ended at 11:39 PM with the Lakers winning by a score of 105-104.
Celtics games tend to be close throughout, but rarely last more than three hours.
The average length of an NBA game is about two hours and five minutes. Games can vary greatly in length, though; some are won early while others get settled down toward the end of play. Half of all games are decided by less than five points per team. There have been games that went past midnight (such as the one mentioned above), but these are extremely rare.
Celtics games usually start between 20,000 and 24,000 fans depending on the home crowd's energy level. This number includes people sitting in courtside seats and standing in the lower bowl. A typical NBA arena has a capacity of about 18,000 to 20,000.
Celtics games are typically very competitive. In 2017-18, there were only six games where one team scored 100 or more points.
Only five minutes All NBA regulation periods will be twelve minutes long. All overtime periods will be five minutes long. All games will have a 15-minute break between halves.
Basketball is a game that requires constant motion and defense of the ball, so it's not surprising that players should wear out over time. Modern basketball players often play more than fifty games during a season, with some playing more than sixty games. A player who does so will have exhausted his ability to increase his endurance and must sit out for rest periods during games.
There are several ways that a player can exhaust himself on the court. He can use energy systems that aren't meant for full-force play, such as high-intensity interval training (HIIT). He can also suffer injuries due to excessive activity. For example, an ankle sprain may cause him to change his game plan, which could lead to increased stress on other parts of his body. Stress fractures are another common injury caused by excessive activity; these fractures occur when your foot, leg, or buttock is subjected to repeated stresses over time.
After a player has exhausted himself, his team will then need to substitute him. This is done by removing him from the game for a period of time, allowing him to recover, and replacing him afterward.
The NBA has always had four twelve-minute quarters since its inception. Using the basis of basketball regulations present in college previous to the league's inception, the NBA determined that 12 minute quarters were the ideal length for a basketball game to run slightly over 2 hours. The first ever NBA game was played on October 11, 1947 with the Boston Celtics defeating the Philadelphia Warriors 91-80 in front of a crowd of 18,000 fans at Fenway Park. The game was not televised and no radio coverage either.
In 1950, after several complaints from players who felt they weren't given enough time on court, the NBA lengthened its quarters from 10 minutes to 15 minutes. In 1953, another complaint led to yet another change: this time, the number of free throws taken during regulation time was reduced from 20 to 10 per team.
In 1954, the last major alteration to the format occurred when the shot clock was introduced by the NBA. Before this change, teams would often wait until the end of the period to substitute players or check on their injuries, which prevented them from playing the most effective basketball. The new system allowed for more consistent gameplay by prohibiting such delays.
All NBA regulation periods will be twelve minutes long. During local games, 2:30 will be allowed between the first and second periods, the third and fourth quarters, and before any overtime session. Otherwise, the period rules apply equally to remote games played across international lines.
The first period of a game will start with a foul shot taken by either team or, if no foul shots are taken during that period, then the first possession of the game will be awarded to the visiting team. The second period will begin with the scoring team electing to take free throws or, if there is still time left on the clock, then the second possession of the game will be played. This process will continue through all 20 periods, unless the two teams reach agreement on a method for continuing the game. If not agreed upon, then the game will be declared a forfeit by the league office and the score will be given to the opposing team.
In addition to the standard four-quarter game, another variation is the double-double game. In this game, each player on the court can achieve two points for a field goal and two rebounds for a personal rebound during the same playing time. Triple-doubles are also possible but require even more offensive firepower from players who can shoot free throws (5 points) and pass the ball (3 assists).
